Preferred term

Coproporphyrinogens  

Type

  • Topical Descriptor

Broader concept

Note

  • intermediates in heme biosyn

Scope note

  • Porphyrinogens which are intermediates in the heme biosynthesis. They have four methyl and four propionic acid side chains attached to the pyrrole rings. Coproporphyrinogens I and III are formed in the presence of uroporphyrinogen decarboxylase from the corresponding uroporphyrinogen. They can yield coproporphyrins by autooxidation or protoporphyrin by oxidative decarboxylation.

History note

  • 91(76); was see under PORPHYRINOGENS 1976-90
